.aPRovi-:MENT m MACHINES Fon PATCHING. PUNCHING, AND EMBOSSINGBUTTON-HOLES OF PAPER-COLLARS.

The Schedule referred to in these Letters Patent and making part of thesame.

To all whom it may concern -Be it known that I, CHARLES LANG, of JerseyCity, in the`Sta'te of New Jersey, have invented certain new and usefulImprovements in Machinery for Patching, Punching, and Embossing theButton- Holes of Paper-Collars and (Juifs, Yand I hereby de'- Clare thatthe following is a full, clear, and exact description of the same,`reference `being had to the accompanying drawing making part of thisspecification.

The object of the present invention'is to greatly simplifyr vandexpedite the operation of cutting out the patches used for strengtheningthe button-holes of paper-collars, pasting them upon the collar, andpunching the button-holes, and this is effected by the combination inamachine of mechanical devices, by`

which all of these operations can be performed by a substantiallysimultaneous operation, thereby very 'inaterially reducing the expenseof a very material part of the work in the manufacture of paper collars.

In the accompanying drawingi Figure 1 represents a side elevation of themachine, the legs having been removed.

Figure 2 is a plan viewof the machine, Acertain of the upper parts oi'the mechanism having been removed to expose the top of one oi the dies.

Figure 3 is a vertical central longitudinal section ofthe machine.

' Figure 4 is a rear elevation of the machine.

Figure 5 shows a modification in the construction of the punches.

Adesignates the frame ofthe machine, which may be of any suitableconstruction. I have shown a table, at the sides of which are uprights,which suppurt the bearings of a inain shaft, C, which shaft derives arotary motion from any suitable motor, and through which shaft motion isimparted to the sev-l eral parts of the machine.

-B designates a carrier, which is arranged to'slide upon the tableportion of the frame.

D D D are punches, and H H H are the dies for said punches. Thesepunches and dies operate together to cut out the patches. A

Within the punches D D D other punches E E E arc arranged, and G G G arethe dies for' the same. These latter punches and dies serve to cut, and,when desired, to emboss the button-holes.

The cutting ends of the punches D and E may be formed of pieces of metalseparate from their Shanks, and secured therein by any suitable means.

In the drawing each punch and shank is represented as made in onepiece,.and is called, in general terms, a punch, and designated by asingle letter.

The shanks of the punches D are made square, to

prevent them from turning, and' they slide in boxes E F F, secured tohorizontal'bars, which are attached to the framein any suitable manner;or, if of other shape, a slot'or pin, or equivalent mechanical device,may be used topi-event their rotating.

and size to the patches resting againstthe bottom of the punch D, andpressing against a shoulder on said punch E, to raise it after it hasbeen pressed down.

The cxtreme lower end of the punch E is the porperforms the cutting ofthe buttomhole.

On the shank of said punch E, a suitable distance above its lower end,is a shoulder', 6, which, after the end of the said punch enters thedie-G, presses against the patch on the collar and embosses the latterwith the device engraved upon the face of die G.

In the drawing a dotted line, to represent stitching, is shown asengraved on the die, for the orna-v mentation of the buttonhole ofthe-collar.

fIhe shoulder 6 may also be engaged if desired.

This shoulder 6 may be omitted, and the opening in the bottom of thepnnch- .Dbe made to, fit the lower end of the punch Ein which case thepunch D, ilrpasting on the patch, will also cmboss-the button-holewithout additional mechanism.

A little above each dieH a plate, c, is secured, which plate relievesthe punch D ofthe strip of cloth as the former rises.

Upon the main shaft G three doublel cams, I J J, are secured. .Thecentral portions of these cams operate the punches E, and the rims orflanges J J constitute another cam, in two parts, which operates thepunch D.

inthe present instance, andin such casetheyare retiacted by springsd,and the punches E are pressed downward by cams I, and retracted bysprlngsf.

or formed on the true arc of a circle struck from'l the centre of saidshaft, er nearly so, andthe cam I is so constructed that itslargest'radius is at that point, as is clearly shown in g. 3, the effectbeingthat the cam J presses the punch D down, which latter carboth,while the projecting portion of the cam I moves the punch E down, whichlatter cuts the button-hole and embosses 'the collar around thebutton-hole.`

In some instances I propose touse frames or straps attached to th'punches, within which the cams worlr, thus giving said punches` apositive motion in both directions,v and dispensing with the use ofsprings.

The machine may bereadily adjusted to operate on collars of differentsizes by sliding the outer cams, punches, and dies to or from thecenter.v

To facilitate this operation I have shown the lower. dies Gr as securedby setlscrews,-airanged in slots,

outer punches D D as secured by screws 7 7, in Slots in the horizontalcrossbars, in the 'upper part of the 'ame, which permit these .bearingsto be shifted to punches and the dies H, which .are attached,these arealso adj usted. v The cams are shifted in the usual -way and secured byAkeys or set-screws.

0n the shaft C is a crank or eccentric, g, which, by means cfapitman-rorh'h, and arm t, gives motion to a rock-shaft, j, as seen in''gsL 1 and 4, and au arm, Je, en the latter, operates the carriage B bymeans of a connecting-rod, Z, pivoted to saidarm k and to a lug ,onthebottom ot' the carriage.l f

AI guide-roller, o, will serve to keep'the` strip of clothiucontact with the wetting-'roller-m; and saidk strip of clothpasses,\preferably, bu'tfnot necessarily,- under a guide-roller, p, andii'orn thence betweenth'e plate c andI dies H,va,nd"`theuce through'thefeedregulating rollers q q.

After the patches have been eut andy applied, the button-holes punched,and the punches raised to repeat' the operation, the feed-rollers q qare rotated, to advance the cloth, by a pawl, 8, which engages with Thepawl is operated by the leverlO, (see lig. 1,) which pawl is lifted by acam,11, secured to a wheel, 12.

The wheel12 receives a rotary motion equal in speed to that of shaft O by anysuitable means.

In thedrawing, a' pulley, 13, on the' shaft O, is shown,for driving apulley, 14, of equal size, ou an intermediate shaft, t, and anotherpulley on shaft t, equal iu size to 12, drivesth'e latter by a belt. Itis essentiall that the motion oi' the wheels 1 2 and 14 coincide exactlywith that derived from shaft C; so,

in practice, I prefertouse chains, which engage with properlyconstructed wheels, and thus I avoid all danger of slipping. In othercases effect tins result by the use of gear-wheels. The wheel 12 may4also be operated directly `froml shaft O by'a chain, o r the pawl-lever10 may have a motionfderived directly from a cam or eccentric on shaftO,.ariang`ed to give the movement at theproper portion of therevolution, in the salue manner as cam Il.

. Hinged to therear edge of thecairiage B are. two or more arms, lr,having forked ends, and "straight plates ,`15, are' also attached-tothecarriage.V The collar is laid upon the platesr and l beyond the edge ofthe carriage B, and slight projections of the plate'on the top ot Bprevent the collarr from rising 1 above the edge.

When the carriage B begins to travel forward the collar or culi' iscarried between the dies G and H; but before it reaches that positionthe plates lr' rise upon the high sides of cams s ou shaft t, and arethereby elevated so that the forked-ends strike against the edge of thecollar, previously operated upon, and push it oli` into any suitablereceptacle.

`When the carriage moves the collar forward Vinto -position between thedies, it comes to rest for a moment,- asbef'ore explained, until thepunches operate npon'aud hold lthe collar, at which time the cam spermits the plates lr to fall, and. the carriage is drawnl backward,pulling the said plates from underneath the collar, and bringingtheminto position to receive t another collar.` The'strips of cloth,which are gummed upon one The operation of the several parts is asfollows: Rotary motionisimparted to the shaft G by the crank 05,01'otherwise, and it revolves in the direction of the arrow. When thecarriage is in the position shown the punches are elevated, a collar is.at such time, placed npou't-he .plates lr 15, and, when the carriagelprogresses, the collar is carried forward upon them between the dies G GG and H H H, while, atv i the saine time, the finished collar is pushedaway, 'as kbefore. explained. At or a little before this time thefeed-rollers q are revolved, and thereby bring fresh.

portions of the wetted gummed cloth under the punches.

' Bytherevolutiou of the shaftG the cams J .T now begin to press .uponthe punches D, which latter descend upoii the cloth, and, in connectionwith dies H, cut out the patches and carry them down and paste them uponthe collar. 'The cams J remain' in thatposition until the cams Ipress'down the punches E,

'which cut the button-holes, and, when desired, enr-- tbossth'e collar.or cu around the same with the de* sign on the dies G. Meanwhile, theplates fr have droppeddown and the carriage has vcommenced its rcl turiifor another collar.

The punches now rise, the plates b pull the collar '0E the punch E, andthe platescstrip the cloth oli" D. The carriage has by this time arrivedat its first position, where it remainsjat rest for a moment, to permitanew collar lto be placedl upon r and 15, and the operation is repeated.

It is evident that rectangular or other shaped pieces of paper may befed into the machine, and afterward cut into collars of the desiredshape. Se, also, asheet of paper may be fed between the dies by rollerssimlilar to q q, and the button-holesbe patched, punched,

and embossed on such paper at intervals, the collar being afterward cutout by another operation.

It will be observed that, by the mechanism described, the collar orcuff, or the paper from which it is to be made, is broughtinto position,and the patches are cut, pasted on the article, and the button-holes cutand embossed, 'all in one 'continuons and nearly simultaneous operationin the same machine.

It is also evident that this machine may be 'used for patching, cuttingthe button-holes in, and embossing paper cuffs, by simply regulatingthenumber and adjusting, the punches, and dies, and carriers.

What I claim as my invention, and desire to secure by Letters Patent,is-

1. The method of cutting out and applying the strengthening patches topaper collars and cuis, and cutting or punching therein thebutton-holes, substantially as herein specified, that is to say, byfirst cutting out the patch, then pasting it upon the co1- lar, and thencutting or punching the button-hole in both patch and collar, the entireoperation being effected by one forward .travel of the punches,and by apractically simultaneous operation;
